Abstract
The application relates to a brake arrangement for braking a flap of a motor vehicle, wherein a connecting element, which is rotatable in a braked manner about a brake axis, for releasing the braking force is provided. It is proposed that a housing accommodating the connecting element and having a first housing part and a second housing part is provided, and that the braking force is adjustable by means of an adjustment movement of the two housing parts with respect to each other.
Claims19
A flap drive for the motorized adjustment of a flap of a motor vehicle, wherein a brake arrangement is arranged in or on a drive train of the flap drive, the brake arrangement comprising:
- a connecting element, which is rotatable in a braked manner about a brake axis, for releasing the braking force;
- wherein a housing accommodating the connecting element and having a first housing part and a second housing part is provided, wherein at least a portion of the connecting element is contained within the housing;
- wherein the braking force is adjustable by an adjustment movement of the two housing parts with respect to each other;
- wherein the housing is assigned an adjustment mechanism for the adjustable fixing of the two housing parts with respect to each other;
- wherein the adjustment mechanism has a screw mechanism, wherein the screw mechanism comprises at least one threaded portion and a mating threaded portion,
- wherein the threaded portion is in, or is configured to be brought into, screwed engagement with the mating threaded portion;
- wherein the flap is configured to be moved between an open position and a closed position over an angular range of angular positions;
- and
- wherein the braking force is equal at two or more than two angular positions of the flap that are separated from each other by at least 50% of the angular range of the flap;
- wherein the connecting element surrounds the brake axis.
A flap drive for the motorized adjustment of a flap of a motor vehicle, wherein a brake arrangement is arranged in or on a drive train of the flap drive, the brake arrangement comprising:
- a connecting element, which is rotatable in a braked manner about a brake axis, for releasing the braking force;
- wherein a housing accommodating the connecting element and having a first housing part and a second housing part is provided, wherein at least a portion of the connecting element is contained within the housing;
- wherein the braking force is adjustable by an adjustment movement of the two housing parts with respect to each other;
- wherein the housing is assigned an adjustment mechanism for the adjustable fixing of the two housing parts with respect to each other;
- wherein the adjustment mechanism has a screw mechanism, wherein the screw mechanism comprises at least one threaded portion and a mating threaded portion,
- wherein the threaded portions is in, or is configured to be brought into, screwed engagement with the mating threaded portion;
- wherein the flap is configured to be moved between an open position and a closed position over an angular range of angular positions;
- and
- wherein the braking force is equal at two or more two angular positions of the flap that are separated from each other by at least 50% of the angular range of the flap;
- wherein a latching engagement between the threaded portion and the mating threaded portion blocks a screwing movement between the first housing part and the second housing part;
- and
- wherein the connecting element surrounds the brake axis.
